CEC323 - PRINCIPLES OF REINFORCED/PRESTRESSED CONCRETE DESIGN FINAL EXAMINATION PROBLEM NO. 1: AT beam has a concrete and steel strengths of 28 MPa and 420 MPa. The live load is (3380 + last 3 digits of your ID number) Pa. while the dead load in addition to concrete's weight is to be (4079 + last 3 digits of your ID number) Pa. The density of concrete is 2400 kg/m³. The slab is 125 mm thick while the effective depth is 600 mm, the total height of T-beam of 675 mm and the bottom width of T beam is 375 mm. The length of the beam is 8 meters. The spacing of beams is 330 cm. Determine the following: a. (35 points) The long-term deflection for 5 years assuming 30% of live load is sustained. b. (15 points) The width of the crack. C. (25 points) the spacing of stirrups using the simplified equation at the following points: ● x=d ● x = 1.0 m . x = 1.5 m x = 2.0 m ● x = 2.5 m PROBLEM NO. 2 (25 POINTS): Design a short column subjected to a nominal axial force of 2000 kN if f'c = 28 MPa and fy = 420 MPa. The steel percentage is maximum.
